A display system is provided, configured to be integrated in an accessory to be worn by a wearer/user as an article of clothing, an item of jewelry, a wristwatch, a pocket watch or any other fashion item. The display system includes: (a) a source of electrical energy, (b) one or more light sources, (e) a source of mechanical information, visual animation or visual presentation, (d) a transformation device for transforming such information or visual animation into a luminous information or visual animation, and (e) a control device adapted to allow the user/wearer to control the activation of the system. In this manner, the system is able to provide a luminous information, visual animation or visual presentation.

A non-electric display system configured to be integrated in an accessory to be worn by a wearer/user as a piece of apparel, an item of jewelry, a wristwatch, a pocket watch or any other fashion item and includes at least one electrical light source for illuminating the display. The light source is hidden when not activated.

A timer kit comprises a battery powered timer and a caddy assembly. The battery powered timer has a colored disk attached to a rotatable shaft. The initial position of the colored disk is manually set by an operator using a positioner accessible through a circular opening extending through a front wall of the caddy assembly. The battery powered timer is removable from the caddy assembly in a generally vertical direction behind the front wall of the caddy assembly. The caddy assembly has a receptable for holding the battery powered timer in a generally vertical orientation behind the front wall of the caddy assembly.

A timepiece display device including a first display element and a second display element superimposed above a fixed part including a main bearing surface, this second display element is subjected to opposing forces exerted, on the one hand by lower return means which tend to bring the second display element closer to the first display element, and, on the other hand, by upper return mechanism which tends to move the second display element away from the first display element without contact between them or else by mechanical spacing device which includes a bearing surface providing a stop bearing function on a stop surface of the second display element, to limit the travel from the second display element to the first display element.

A watch part includes a base material having a watch part shape and containing silicon as a primary component and a light-reflecting layer stacked on the base material, wherein the light-reflecting layer includes a first layer, a second layer, and a third layer which are successively stacked in this order from the base material, the first layer is formed using silicon oxide, the second layer is formed using silicon, and the third layer is formed using a material having a refractive index of 1.7 to 2.7.

A construct having an aesthetic form is adapted to please a wearer and to be worn by the wearer. The construct provides a structure having a wearer connection element such as a ring, a chain, a wristband, a pin, a clasp, a clip, and a body piercing element. The functional elements including a fluid reservoir in which at least two fluids are disposed, and a motion generation system are integrated on the structure, The motion generation system is functionally affixed to the structure so as to agitate the at least two fluids, causing a visual animation effect. The construct, in particular jewelry, may have incorporated therein one or more channels and/or reservoirs containing one or more fluids wherein the fluids as well as the forms and surface treatments of channels/reservoirs are selected possess physical properties so as to promote a defined interaction with the one or more fluids. The interaction influences the visual appearance of the device, such device optionally being made at least in part of precious metals, natural components such as pearls, and/or precious stones.

A mechanical stop and start system for a function of a timepiece, including a mass, mounted so as to be able to move on a frame, between a first and a second end position, which are defined respectively by a first stop and a second stop. The mass portion moves in a bistable manner, under the effect of gravity, tensioning a spring between the first and second end positions, and relaxing the spring between the second and first end positions.

Provided is a timepiece including, in addition to a crystal, the following external elements: a back (2), a middle part (1), a dial (3), and two bracelet strands (30), at least one of these external elements includes a body formed of a first portion made of a first opaque material and of a second portion made of a second partially transparent or translucent material. The first material being integral with the second material and the timepiece also includes at least one light source (10) producing light which passes through the second portion made of a partially transparent or translucent ceramic material comprising zirconia.

A timer kit comprises a battery powered timer and a caddy assembly. The battery powered timer has a colored disk attached to a rotatable shaft. The initial position of the colored disk is manually set by an operator using a positioner accessible through a circular opening extending through a front wall of the caddy assembly. The battery powered timer is removable from the caddy assembly in a generally vertical direction behind the front wall of the caddy assembly. The caddy assembly has a receptable for holding the battery powered timer in a generally vertical orientation behind the front wall of the caddy assembly.

A method for manufacturing a luminescent hand for a horological movement, preferably for a watch. The method includes providing a support comprising a light guide and structuring an emergent surface of the light guide so as to extract a maximum amount of light from the luminescent hand. The luminescent hand includes, over a lower face, a layer of luminescent material including one or more deposit(s) of fluorescent material, opposite a light source. The light source is laced at locations close to the axis of rotation or away from the axis of rotation but at a distance from the luminescent material. Thus, the light source is not placed on the luminescent hand.
